A igualdade de Auslander-Buchsbaum.
The classical Auslander-Buchsbaum equality furnishes a relationship between two fundamental algebraic nvariants: depth and homological dimension. Our goal will be to prove such result and to apply it into the context of logarithmic derivations.

Iwasawa theory of p-adic Lie extensions
… R-modules. Then a local duality theorem and the Auslander-Buchsbaum equality for R are proved. In the second, arithmetic part we show the existence of certain pseudo-isomorphisms of global Iwasawa modules, we study the µ-invariant and we prove for some Galois modules that they do not contain any …
